3 Claims. (Cl. 30-158) particular directed to certain *novelimprovements'jin the :design and construction thereof. It .is :among theobjects of 'my invention to provide a safety razor comprising a minimumnumber of parts. u

Another :object is to provide a safety razor which mayibe inexpensivelyproduced.

' A further object fis to provide a safety razor *which ':may 'tbe'rapidly' assembled and disassembled, and which idoes not requiredisassembly' for removal or replacement of the blade, :or "forcleaningroperations.

An additional 0'bj ect is :to provide a structure of the class'indica'ted, resulting :in economy of 5 .of the safety razor shown inFig. 2 illustrating its closed or clamped position.

Fig. .5 is a view of the upper portion .of the safetyrazor shown in Fig.4 but illustrating :the same'i-n open position for removaLor replacementof ,the razorbla'de.

The hollow generally cylindrical handle -10 is externallythreaded at itsupper end as indicated at H to receive the collar l2 internally threadedas at l3 of the guard member 94. The guard member 14 may be providedwith teeth It extending along its anterior lateral edge and the terminallugs or projections l6 which serve to alignthe inserted razor blade !1.The pins 18 serve additionally to locate and align the blade I! whichmay be provided with holes 2t, specially arranged to fit over the pins!3. The guard member i4 is formed in such a manner as to present arearwardly projecting portion 2! hav ing its lower end provided with thecollar 12 internally threaded as hereinbeiore described. I

The member 2|v is also provided with vertical upwardly extending flanges22. The clamping member 23 may be pivotally attached to the flanges 22of the guard member M, by means of a threaded pin 24 which passesthrough oppo- 2 sitely-disposed holes 2-5 .in the router flangesgfi .ofth'exclamping member 523 and the correspond- ;ing holes 21 .of theflanges 322 of the guard inember 14. The clamping member =23 may have alength equal to that :of the guard :member 14, and be provided with:downwardly projecting lugs '28, which abut 'the en'ds 29 o'i'theigu'ardimember I 4, and which 'are in 'alignm'ent with the "terminallugs 2i 6 in the 7 closed position of thesa'fety razor. The clampingmember 23' maybe provided with a downwardly eXtending portion 3"centrally disposed between the outer fianges iii-and defining:anuangularly inclined' raceway or channeI Sl having a aconstrictedlower portion "for the purposes to.'be hereinaiterindicated.

The cylindrical handle is internally-threaded as at Z32 to receive:ascrew spindle I33 threaded as at 34. The -screw spindIeBS- terminatesupwardly in azstructure adopted.forcomplementary insertion within theraceway or channel 3|. The terminaLp'ortioniof the screw spindle dz-mayconveniently ta ke the form ofa ball tip 35, -=as ishown .inhthedrawings; t

Ugpon a-sse'm'bly, the ball-tip 3.5 of the screw spindle 3-3 is retainedwithin the -angularly-in- :clined 'charrnel 31 of the clamping member23. Pivotal :movement 0f @the "clam-ping member 23 with respect "to theguard member M may be achieved by advancement :ofthe screw spindle '33.This movement 'imay conveniently :be a'coomplish'ed v.by-iro'tatingthe:knurled lower end 31 of the screw-s-pindle iit. -Removalzof .the blademay be efieoted by rotating the iknu'rle'd end 31 of the screw-spindleifii in 'areverse direction to move the clamping meinber I 23 away fromthe guard member 4, thereby f-reeingtheblade Pl '1, as illustrated inFig. 5.

The alternative embodiment of the principle of my invention showing amodification of structure and co-action between the handle 40, thenon-threaded spindle 4 I, and the clamping member 23, is illustrated inFig. 3. This arrangement contemplates the use of a bayonet slot 42disposed conveniently at the lower end of the handle 40 adapted toengage and retain a bayonet pin 43 projecting from the spindle 4|. Inthe illustration thereof, as shown in Fig. 3, the razor is in the closedposition analogous to that illustrated in Fig. 4 for the previouslydescribed embodiment. The razor may be opened so as to separate theclamping and guard members by turning the knurled end 44 of the spindle4| (which is not threaded as contrasted with the threading 34 of thescrew spindle 33) thereby bringing the pin 43 into alignment with the 1.A safety razor comprising a handle having a hollow bore, a guard memberhaving a longitudinally disposed bed for a razor blade and a centrallypositioned and rearwardly projecting section adapted to engage saidhandle, said section having a pair of upwardly disposed and spaced-apartflanges, a blade clamping member having a centrally positioned andrearwardly projecting section, said section of the clamping memberhaving a pair of downwardly disposed and spaced-apart flangesysaidsection of the clamping member also having a centrally disposed portionwith an arcuately and downwardly extending slot, said slot opening intoa second larger slot of substantially circular cross section, .a pinextending through all the aforesaid flanges whereby the guard member andclamping member are held in pivotal connection, a spindle extendingwithin said handle, the upper end of said spindle having a taperedportion carrying a ball, the said ball being held slideably in theaforesaid circular slot and the tapered portion within the firstmentioned slot, whereby motion of said spindle serves to move theclamping member, thereby to look a blade positioned be tween saidclamping member and the guard member.

2. A safety razor comprising a tubular internally threaded handle, aguard member having a longitudinally disposed bed for a razor blade, anda centrally positioned and rearwardly projecting section adapted toengage said handle, said section having a pair of upwardly disposed andspaced-apart flanges, a blade clamping member having a centrallypositioned and rearwardly projecting section, said section of theclamping member having a pair of downwardly disposed and spaced-apartflanges, said section of the clamping member also having a centrallydisposed portion with an arcuately and downwardly extending slot, saidslot opening into a second larger slot of substantially circular crosssection, means for pivotally connecting the pair of flanges of therearwardly projecting section of the guard member with the pair offlanges of the rearwardly projecting motion of the clamping memher, aspindle threadedly engaged within the internal threads of the handle andextending therethrough, the upper end of said spindle having a taperedportion carrying a ball, the said ball being held slideably in theaforesaid circular slot and the tapered portion within thefirst-mentioned slot, whereby motion of said spindle serves to move theclamping member thereby to look a blade positioned between said clampingmember and guard member.

3. A safety razor comprising an internally threaded tubular handle, aguard member having a longitudinally disposed bed for a razor blade, anda centrally positioned and rearwardly projecting section adapted toengage said handle, said section having a pair of upwardly disposed andspaced-apart flanges, a blade clamping member having a centrallypositioned and rearwardly projecting section, said section of theclamping member having a pair of downwardly disposed and spaced-apartflanges, said section of the clamping member also having a centrallydisposed portion with an arcuately and downwardly extending slot, saidslot communicating with a channel parallel with said slot and of largertransverse cross section than the cross section of said slot, means forpivotally coonnecting the pair of flanges of the rearwardly projectingsection of the guard member with the pairs of flanges of the rearwardlyprojecting section of the clamping member, a spindle threadedly engagedwithin and extending through said handle, said spindle terminating in asection, of reduced diameter, extending through the aforesaid slot andcarrying a terminal tip of larger diameter than the said section, saidtip being held in slideable engagement within the aforesaid channel,whereby motion of said spindle serves to move the clamping memberthereby to lock a blade positioned between said clamping member andguard member.
